Semi automatic process for cold saponification of pure vegetable oil providing for the production of a pure soap containing more than 5 % of glycerine and free of secondary waste, characterized by the pre-heating of oils used at a temperature of 50 DEG C approximately, in a closed reactor fitted with stirring means, incorporating the appropriate reagents and additives, the reaction being auto-catalyzed without further heating, and at the end of the reaction the temperature is maintained at about 80 DEG C in order to keep a sufficient viscosity, and progressively all the content of the reactor is emptied and, by circulating water at a temperature lower than 50 DEG C the soap paste obtained is refrigerated so that the latter forms a mass of soap like soap cake which is then cut to the desired dimensions. The method according to the invention provides for the production of a hard soap with a vegetable washing base while optimizing the cost price/quality ratio.
